In taking his aim Kingozi modified his usual custom because of the distance. When one can get his beast broadside on, the most immediately fatal shot is one high in the shoulder, about three-quarters of the way up. That drops an animal dead in his tracks. The next best is a bullet low in the shoulder. Third is a really accurate heart shot. This latter is always fatal, of course; but ordinarily the quarry will run at racing speed for some little distance before falling dead. In certain types of country this means considerable tracking, may even mean the loss of the animal. Next comes anywhere in the barrel forward of the short ribs--a chancy proceeding, and one leading to long chases. After that the likelihood of a cripple is too great.

Now it is evident that one must aim at what he can be sure of hitting. The high shoulder shot is all right if the distance is so short that one can be absolutely certain of placing his bullet within a six-inch circle. Otherwise the chance of over-shooting--always great--becomes prohibitive. The low shoulder shot increases the circle to from eight to twelve inches, with the chance outside that of merely breaking a foreleg, grazing brisket, or missing entirely under the neck. The heart shot--or rather an attempt at it--is safer for a longer range, not because the mark is larger, but because even if one misses the heart, he is apt to land either the shoulder or the ribs well forward. The only miss is beneath, and that is clear, as the heart is low in the body. And at extreme ranges, the forward one-third of the barrel is the point of aim. It should only rarely be attempted. Unless a man is certain he can hit that mark, every time, he is not justified in taking the shot.

This principle applies to every one: as well to the beginner as to the expert. The only difference between the two is the range at which this certainty exists. The tyro's limit of absolute certainty for the heart shot may be--and probably is--a hundred yards; for the high shoulder it may be as near as thirty. This takes into consideration his inexperience in the presence of game as well as his inaccuracy with the rifle, and it keeps in mind that he must hit that mark not merely nine times out of ten, but every time. If he cannot get within the hundred yards by stalking, then he should refuse the chance. As expertness rises in the scale the distances increase. Provided there were no such things as nerves, luck, faulty judgment, and the estimate of distances one man should be as mercifully deadly as another. Naturally the man who had to stalk to within a hundred yards would not get as many shots as the one who could take his chance at two hundred. This conduct of venery is an ideal that is only approximated. Hence misses.

But even if a man lives rigorously up to his principles and knowledge, there are other elements that bring in uncertainty. For one thing, he must be able to estimate distance with some degree of accuracy. It avails little to know that you can hit a given mark at two hundred and fifty yards, if you do not know what two hundred and fifty yards is. And here enter a thousand deceits: direction of light, slope of ground, nature of cover, temperature, mirage, time of day, and the like. An apparent hundred yards over water or across a cañon would--were, by some dissolving-view-change, bush-dotted plain to be substituted--become nearer three hundred in the latter circumstances. There is a limit to the best man's experience; a margin of error in the best man's judgment. Hence more misses.

There is only one method for any man to acquire even this proximate skill; and that requires long and patient practice. It is this: he should sight over his rifle at a wild animal, noting carefully the apparent relative size of the front sight-bead and the animal's body. He should then pace the distance between himself and that animal. After he has done this a hundred times, he will be able to make a pretty close guess by marking how large the beast shows up through the sights. That is, for that one species of game! In Central Africa, where in a well-stocked district there are from twenty to thirty species, the practice becomes more onerous. This same practice--of pacing the distances--however, has also trained a man's eye for country. He is able to supplement the front-sight method by the usual estimate by eye. Most men do not take this trouble. They practise at target range until they can hit the bull's-eye with fair regularity, miss with nearly equal regularity in the hunting field, and thenceforth talk vaguely of "missed him at five hundred yards." It must have been five hundred. The beast looked very small, there was an awful lot of country between him and it, and "I wasn't a bit rattled--cool as a cucumber--and I know I never miss an object of that size at any reasonable range." He was right: he shot as deliberately as he ever did at the butts. He missed, not because of the distance, but because he did not know the distance. It was exactly the range at which he had done the most of his practice--two hundred yards!

All these considerations have taken several pages to tell. Kingozi weighed each one of them. Yet so long had been his experience, so habitual had become his reactions, that his decision was made almost instantly. A glance at the intervening ground, another through his sights. The top of the bead covered half a zebra's shoulder. The distance was not far under or over three hundred. Kingozi knew that, barring sheer accident, he could hit his mark at that distance.

The animals meantime were moving forward slowly along the three diverging trails. The last of them had left the water-hole. Kingozi nodded to Simba. Simba, understanding from long association just what was required of him, rose slowly and evenly to his feet.

The apparition of this strange figure on the skyline brought a score of animals to a stand. They turned their heads, staring intently, making up their minds, their nostrils wide. Kingozi, who had already picked his beast and partially assured his aim, almost immediately squeezed the trigger.

Over a second after the flat crack of the rifle a hollow plunk indicated that the bullet had told. It was a strange sound, unmistakable to one who has once heard it, much as though one brought a drinking glass smartly, hollow down, into the surface of water.
